Now, this want of apparent Truth and Reasonableness, is not only where the Notions and Precepts giv’n, are in themselves such as either in Whole, or in Part, are not True or Rational; but also (oftentimes) where they are altogether conformable to right Reason:  In which cases, the want of apparent Reasonableness, proceeds from a defect of such Antecedent Knowledge in those who are design’d to be instructed, as is necessary to the seeing their Reasonableness of the Instructions giv’n them; that is to say, To their discerning the conformity with, or evident deduction of such Instructions from some Truths which are unquestion’d by them:  the which should be the Principles of True Religion, so clearly made out to them, as to be by them acknowledg’d for Verities.  Religion being (as I shall take it at present for granted) the only sufficient ground or solid support of Vertue; For the belief of a Superior, Omnipotent Being, inspecting our Actions, and who will Reward or Punish us accordingly, is in all Men’s Apprehensions the strangest, and in truth the only stable and irresistible Argument for submitting our Desires to a constant Regulation, wherein it is that Vertue does consist.

How far Natural Religion alone is sufficient for this, is very fit to be consider’d:  But I conclude that among us, there are few who pretend to recommend Vertue, but who do so either with no respect at all to Religion, and upon Principles purely Humane, or else with reference to the Christian Religion.  The first of these, it is already said, will be ineffectual; and it is no less certain that the Christian Religion cannot be a solid Foundation for Vertue, where Vertue being inculcated upon the Declarations of the Gospel, those who are thus instructed, are not convinc’d of the Authority and Evidence of that Revelation; which but too commonly is the Case:  Instructors, instead of Teaching this necessary previous Knowledge of Religion, generally, supposing it to be already in them whom they instruct, who in reality neither have it, or have ever been so before-hand Taught, as to make it a reasonable Presumption that they should have it.  Whence all the Endeavours of making them Vertuous in consequence of their Christianity, are but attempting to raise a real Superstructure upon an only imaginary Foundation; for Truths receiv’d upon any other Ground than their own Evidence, tho’ they may, perhaps, find entertainment, yet will never gain to themselves a sure hold upon the Mind; and so soon as they become troublesome, are in great danger of being question’d; whereby whatever is Built upon them, must be likewise liable to be suspected for fallacious:  And however empty Declamations do often-times make livelier impressions upon Young People than substantial Reasoning, yet these impressions are, for the most part, easily effac’d; and especially are so out of their Minds who naturally are the capablest of right Reason; as among other instances appears in this, that prophane Wits do often even railly Women of the Best Parts (Religiously Bred as they call it) out of their Duty:  These not seeing (as they should have been early Taught to do) that what they have learn’d to be their Duty is not grounded upon the uncertain and variable Opinion of Men, but the unchangeable nature of things; and has an indissolvable Connection with their Happiness or Misery.
